pc powersupply in PMG4 AGP? - 10/28/04 01:56 PM

Hi
I am new to this forum, but have been wanting to mod a powermac into a silent "cube-like" music server/digital photo frame in my living room. I just picked up a g4 AGP 350/576/10/dvd used for $165. It is so noisy--particularly the PSU hum (not the fan)and the little fan on the ati rage pro!!! I am used to an imac (flat panel 15") and an ibook g4.
the way i see it the secret of the cube is that it has an external, quiet PSU. if you dont put all that heat in the same box as the cpu and other electronics, the cooling problems are much simpler. here's the plan
Step 1 replace ati card with radeon 7000 with heatsink only. replace cpu with powerlogix g4 800 with heatsink only (fastest without fan that i could find)
step 2 separate cpu from PSU by removing all parts from case
step 3 create separate enclosures for cpu,psu,drives
step 4 eliminate fans completely (except for possibly just slowing down psu fan)...add heat sinks with major ventilation to all 3 enclosures.
step 5 splice in longer connections to allow PSU to be out of sight and away from workspace (12"-24")

step 6 possibly ....
replace psu with aftermarket quieter one....????is this possible???
any of you experienced guys have any suggestions i would appreciate them
thanks

G4noise.com - A site devoted to noisy G4's

What you could do is replace the fans with variable fan speed ones, and take temp. measures. Tweak the fans to the lowest point that your computer can handle, and that should help out a lot with the fan issue. Those things were just loud to begin with. Also you could drop some noise dampening material, though it could affect the airflow depending on how you do it. I know a lot of people replaced the P/S's with quieter ones and that kills a lot of the noise. There are a lot of options, though the forums over @ G4 noise are a trove. It's oudated now, but if you do anything, I would love to see a mod guide for what you do for our records.

as well, please remember to take plenty of pictures for a mod guide on the site. I would love to see this mod. Have you decided what kind of enclosure you are going to use? What are the decision factors relating to the picture frame or the music box? I have always loved the music box. They can be slightly larger and there are many more options with them. plus, you could always make a wireless pictureframe with some technology that is out now to transfer video wirelessly. Then it could be a music box/picture frame, picture server laugh
